A superb novel, at least as good as Gautreaux's earlier work, "The Clearing". It begins with Sam Simoneaux, a Cajun, landing in France on Armistice Day, and his unit is assigned to clear unexploded ammo from 2 square miles of battlefield. They have no training, and they take casualties. One day they find an old French artillery piece, and they decide to fire it at a large pile of shells they've stacked up. Instead, they hit a house, killing all its occupants save for a young girl. Sam befriends her, but of course there is no way he can do much for her. There are tens of thousands of orphans all over France.
Soon, we find out why he took such an interest: his family were murdered in a revenge attack when he was six months old. His father had saved his life by throwing him into the iron stove just before he was killed, and his uncle found him the next day. Although his uncle and aunt proved loving and wise parents, and he never found out about his real parents until he was six or seven, he always knew that somehow he wasn't quite the same as the cousins he was raised to think of as brothers and sister.
The main story starts a few years after the war, when Sam is married and working as a floorwalker in a department store (which sounds exactly like one I worked for in Michigan in 1959!). He likes his job, and is looking forward to a promotion, when a young couple tell him their 3-year-old daughter, Lily, has gone missing. Sam starts looking right away, but fails to order the doors locked in time; when he finds the girl having her hair cut in a dressing room on the fourth floor, he is hit from behind and rendered unconscious. Four days later, when he recovers enough to go into work, he gets the sack. The owner of the store tells him he can have his job back if he finds the girl.
For most people, this wouldn't be sufficient motivation to leave one's loving wife without any money and embark on a year-long quest. He signs on as third mate on the Ambassador, a decrepit Mississippi stern-wheeler where Lily's parents work. Lily is a precocious singer, so the theory is that whoever stole her must have seen her on the boat. The Ambassador makes a lot of money offering romantic days and evenings afloat, introducing America to black musicians and New Orleans jazz. Patrons bring aboard moonshine, and one of Sam's first jobs is to ensure that all knives and guns are checked in before customers board. He is one of the crew members responsible for breaking up fights. But wherever they land, Sam gets ashore to find out if he can a lead on Lily.
That's enough to get you started. Buy the book--I'd be very surprised if you regretted it. I may be a bit biased--I grew up in Michigan, and the deep south has long been a source of endless fascination. There were still a few Civil War veterans alive when I was young. And for all the propaganda you get about the deep south, I fell in love with it when I got to know it. Gautreaux evoked my memories of hot summer nights before the days of air-conditioning--when you sat out on the porch in the dark, drinking lemonade and listening to the crickets. Although this will be lost on Britons, this is a wonderfully atmospheric book, and one which will register with musicians everywhere. But most of all, it's a superb novel about what it means to grow up without parents, and why families are so important. It's also a very wise novel about revenge--the surest way to compound an injury is to become obsessed with revenge.
